Industrial-grade airflow
The Delta QFR1212GHE is a 120 mm by 38 mm axial fan built for workstation and server CPU cooling. It runs on 12 V DC at 2.70 A and spins at 6000 RPM to deliver 210.38 CFM of air volume. The high-precision double ball bearing and PBT plus glass-fibre frame are rated for 80,000 hours at 25 °C.
High static pressure headroom
At 21.60 mmH₂O the fan pushes air through dense heatsinks and restrictive chassis paths without stalling. The 64 dB-A noise level is the trade-off for that pressure, so it suits rackmount or server rooms rather than quiet desktop builds. Operating range spans -10 °C to 70 °C with a ±15 % power tolerance.
4-wire B3 connector limits
The proprietary B3 connector carries power, ground, tachometer and PWM control on a single header. It requires a matching motherboard or controller pin-out; standard 4-pin PWM headers are not electrically compatible. Insulation resistance exceeds 500 megohms and the unit withstands a 500 V hi-pot test for one minute at 0.5 mA leakage.

Questions about this item
Will the 4-wire B3 connector on this 12038 fan work with my older motherboard's 3-pin header?
The 4-wire B3 connector fits standard 4-pin PWM headers; on a 3-pin header it will run at full 6000 RPM without speed control.
How can I confirm the fan is spinning at the rated 6000 RPM after installation?
Monitor the RPM reading in BIOS or fan-control software; it should report close to 6000 RPM under full PWM duty.
Does the box include mounting screws or a PWM splitter cable for the QFR1212GHE?
The package contains only the fan unit itself; mounting screws and any PWM splitter cables must be purchased separately.
